【摘要】 本文基于SIMSEN仿真软件建立了汽轮发电机系统瞬态分析的仿真模型,模型中考虑了电机电磁系统、机械系统、网络元件等的影响。并对一台650MW汽轮发电机不同端电压时的空载短路情况进行了仿真计算,得到了发电机的定子电流、励磁电流、电磁转矩及轴力矩随时间的变化曲线及规律。更多还原

【Abstract】 The simulation model of the turbogenerator and power system in transient conditions is set up by means of software SIMSEN in this paper.The electromagnetic system,mechanical system of machines and elements of power system are considered together.According to the calculation for a 600MW turbogenerator with various terminal voltage magnitudes at no load conditions,some short-circuit characteristic curves,e.g.variations of stator current,field current,electromagnetic torque and axis torque with time are obtained.更多还原
